It is an object of the present invention to provide a gel-forming composition which permits on-site administration and can form a gel exhibiting prescribed strength and sustained drug release, devices for the administration thereof, and a kit for medical use. A gel-forming composition which is composed of the first composition comprising a drug, a first gelling agent represented by the general formula (I) and the like, and the first diluent and the second composition comprising the second gelling agent represented by the general formula (I) and the like and the second diluent; and application devices and kits for medical use, which can hold the gel-forming composition. X1 - (OCH2CH2)n - X2 (I) wherein X1 and X2 are each -R1COONHS (wherein R1 is C1-7 alkylene), -COR1COONHS, -NOCOR1-R2 (wherein R2 is maleimido), -R1NH2, -R1SH, or -CO2PhNO2, and n is an integer of 80 to 1000.
本发明的目的是提供一种允许现场给药并能形成具有规定强度和持续释药的凝胶的凝胶形成组合物、其给药装置和医疗用试剂盒。一种凝胶形成组合物,它由包含药物、通式(I)代表的第一胶凝剂和类似物以及第一稀释剂的第一组合物和包含通式(I)代表的第二胶凝剂和类似物以及第二稀释剂的第二组合物组成;以及可容纳凝胶形成组合物的施用装置和医疗用试剂盒。X1-(OCH2CH2)n-X2(I) 其中X1和X2各自为-R1COONHS(其中R1为C1-7亚烷基)、-COR1COONHS、-NOCOR1-R2(其中R2为马来
酰亚胺基)、-R1NH2、-R1SH或-CO2PhNO2,且n为80至1000的整数。
